An Astronomical Unit is a unit of measurement of distance, frequently used to measure inter-planetary distances.
- It is an astrographic scale measurement.
- It is a standard Imperial metric.
Description (Specifications)
One Astronomical Unit is about 150 million kilometers (or, more precisely, 149¨597 870 691 ± 30 meters), or about 93 million miles.
- The standard abbreviation is AU.
History & Background (Dossier)
Because the definition of a Parsec relies upon the Astronomical Unit, the AU has become a standard unit of measurement within the Imperium.
Imperial vs. Solomani Astronomical Unit Usage
The Solomani define the Astronomical Unit as the distance between Terra and Sol, the system's primary star.
Modern Imperial usage bases the AU on the distance between Capital and its sun, which happens to have an almost identical orbital distance to that of Terra around Sol. This definition of the AU was broadly adopted following the Solomani Rim War, in order to avoid the use of specifically Terrocentric metrics.[1]
